ROBERT NAUMANN, OE NEW YORK, N. Y.

PRINTING-PRESS ATTACHMENT.

SPECIFICATION' forming part of Letters Patent No. 692,065, dated January 28, 1902,.

Application filed October 18,1901. Serial No. 79.167. (No model.)

To @ZL whom t may/concern,.-

Beit known that I, ROBERT NAUMANN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Im proved Printing-Press Attachment, of which the following is a full, clear, and exact description.

This invention relates to improvements in ink-supplying attachments for all printingpresses of the type having a rotary inkspreading disk; and the Object is to provide an inkfont that may be quickly attached to or removed frein a press, so that diderent inks or changes from one color to another may be made Without delay, and, further, to provide a simple means, actuated by a movement of the press, whereby the ink-su pply for the rollers will be forced out evenly and with uniform pressure; and still another object is to provide a means for regulating the amount of ink discharged, resulting in a considerable saving of time.

I will describe a printing-press attachment embodying my invention and then point out the novel features in the appended claims.

Reference is to be had, to the accompanying' drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation showing an inking device embodying my invention as applied to a press. Fig. 2 is an opposite side view showing the means for actuating the inkdischarging plunger. Fig. 3 is a longitudinal section of the font or reservoir, and Fig. 4 is a cross-section of the reservoir.

Referring to the drawings, 1 designates a portion of a printing-press frame, and 2 indicates one of the arms for carrying the inkingrollers over the rotary spreader-disk 3, operated in the usual manner. Attached to the frame portion 1 is a plate 4, to which is removably attached the ink-font 5. As here shown, this ink-font is cylindrical and has a removable front end piece 6, the upper portion 7 of which is inclined substantially to the its opposite side it is provided with recesses 13 to receive lugs 14 on the end of a clamping-bar 15, which is engaged by a set-screw 16, passing through an upwardly-extended arm 17, attached to a bracket 18 on said plate 4. By this arrangement it is evident that the font may be quickly removed and replaced by another one containing a different-colored ink when desirable. Movable in the font is a follower 19, which at its rear side is loosely engaged by a plungerhead 20ct' a size to pass readily through ari opening 21 at the rear end of the font. Extending from this plunger-head is a rack 22, engaging with a pinion 23 at one side of the plate 4, while on the shaft ot' said pinion, at the opposite side of the plate, is a gear-wheel 24, meshing with a pinion 25 on the shaft of a gearwheel 26, which engages with a pinion 27 on the shaft ot' a ratchet-wheel 23. Mounted to `swing on the shaft of the ratchet-wheel is an actuating-lever 29, to an upward extension 30 of which is pivoted a dog 31which engages with the ratchet-wheel.` A stopdog 32, engaging with the ratchet-wheel, prevents any possible backward movement of the device.

fThe rear end of the lever 29 is designed to be inoperative by raising the dog 31, so that by a movement of the lever 29 the dog will pass freely over the teeth of the ratchet-wheel. For this purpose I provide a shifting lever 36, pivoted` to the plate 4 and adapted to be raised into connection with the forwardlyprojecting arm 37 of the dog and hold the dog out of engagement with the ratchet-wheel. When in its lowermost position, the lever 36 rests on a pin 33.

In operation when the inking-rollers reach a position near the lower portion of the disk 3 the roller 33 will engage the lever 29, causing a movement of the same to actuate the plunger 19 and force a desired amount of ink through the openin 9, so that each roller will take a portion of ink and spread it over the surface of the form-bearer, and the rollers on their upward movement will give an extra or perfect digesting or distribution.

Having thus 'described my invention, I claim as new and desire to secure by Letters Patentl. An inking attachment for a printingpress, comprising a font having an opening at one end for the discharge of ink, a follower for operating in the font, and means actuated bya movement of the press for operating said follower, the font being arranged to discharge ink onto an inking-roller passing over the same, substantially as specified.

2. An inking attachment for a printingpress, comprising an ink-font having an inclined forward end provided with an outlet for ink, a follower arranged in the font, a plunger for removably engaging with said follower, and means actuated by a movement of the press for moving said follower, substantially as specified.

3. An inking attachment for a printingpress, comprising a font having an outletopening at one end, a plate attached to the printing-press frame, removable connections between said font and the plate comprising an arm mounted on the plate, a clam ping connection between said arm and the font, a follower in the font, and means actuated by a movement of the press for moving said follower, substantially as specified.

4. An inking attachment for a printingpress, comprising an ink-font having a discharge-opening at its forward end, a follower operating in the font, a plunger removably engaging with said follower, a rack extended outward from the plunger, a ratchet-wheel, a lever loosely mounted on the shaft of said ratchet-wheel and adapted to be operated by a movement of the printing-press, a dog carried by said lever for engaging with the ratchet-wheel, and gear connections between said ratchet-wheel and said rack,substantially as specified.

5. An inking attachment for a printingpress, comprising an ink-font having an outlet at its forward end, a follower operating in the font, a plunger removably engaging with the follower, a rack extended outward from the plunger, a pinion engaging with said rack, a gear-wheel on the shaft of said pinion, a ratchet-wheel, gear connections between said ratchet-wheel and said gear-wheel, a lever loosely mounted on the shaft of the ratchetwheel, a part carried by a moving part of the press for engaging with said lever to operate it, a dog carried by the lever for engaging with the ratchet-wheel, and a back-stop dog engaging with the ratchet-wheel,substantially as specified.

6. An inking attachment for a printingpress, comprising a font having an outlet at its forward end, a follower operating in said font, a rack for forcing said follower forward, a ratchet-wheel, gear connections between said ratchet wheel and the rack, a lever mounted to swing on the shaft of the ratchetwheel, means for adjusting the throw of said lever, a device carried by a movable part of rthe press for actuating said lever in one direction, a dog carried by the lever for engaging with the ratchet-wheel, and means for shifting said dog out of operative connection with the ratchet-wheel, substantially as specified. Y

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
